This study tests two experimental mRNA vaccines (mRNA-1403 and mRNA-1405) designed to prevent norovirus, a highly contagious virus that causes vomiting and diarrhea. Around 1,400 healthy adults aged 18 to 80 will receive either a vaccine or a placebo to check safety and how well …

This study tests a new mRNA booster shot (mRNA-1345) for RSV in adults aged 60 and older who received a prior RSV vaccine at least one year ago. Researchers will check for side effects and measure how well the booster strengthens the immune system. The goal is to see if revaccina…

This study tests two updated COVID-19 vaccines (mRNA-1283 and mRNA-1273) in 30,000 healthy adults aged 50 to 64 who are not at high risk for severe COVID-19. The goal is to see if these vaccines can prevent symptomatic COVID-19 compared to a placebo. Participants will be monitore…

This study tests an experimental mRNA vaccine (mRNA-1345) against respiratory syncytial virus (RSV) in 360 pregnant women. The goal is to see if vaccinating mothers during pregnancy can safely boost their immunity and pass protection to their babies. Participants receive either t…

This early-stage study tests an experimental mRNA vaccine called mRNA-1195 in 482 healthy adults aged 18 to 55. The goal is to see if the vaccine is safe and triggers an immune response against the Epstein-Barr virus, which causes mononucleosis and is linked to certain cancers. P…

This study tests two new mRNA vaccines in children aged 5 months to 2 years. One vaccine targets RSV alone, the other targets both RSV and hMPV—two viruses that can cause serious breathing problems in young kids. The main goal is to check safety and how well the vaccines trigger …

This early-phase study tests an experimental mRNA cancer vaccine (mRNA-4157) in 161 people with solid tumors. The vaccine is designed to train the immune system to attack cancer cells. Some participants receive the vaccine alone, while others get it with the immunotherapy drug pe…

This early-stage study tests an experimental mRNA medicine called mRNA-3745 in 15 people with glycogen storage disease type 1a (GSD1a), a rare genetic condition that causes dangerously low blood sugar. The treatment aims to help the body produce a missing enzyme to better control…

This study is tracking over 4,200 people in South Korea who received Moderna's SPIKEVAX COVID-19 vaccines to see if any side effects occur over time. The goal is to understand the long-term safety of these vaccines when used in routine medical care. Participants are aged 12 or ol…
